Answer

Brief Explanations:

DNA (Deoxyribonucleic acid) serves as the primary molecule for storing and transmitting genetic information in living organisms. Its core functions include:

  1. Protein Synthesis Instructions: DNA contains genes that provide the specific codes for building proteins, such as keratin.
  2. Heredity: DNA is the medium through which traits (like eye or fur color) are passed from parents to offspring.
  3. Biological Regulation: DNA provides instructions for creating various functional molecules, including antibodies and enzymes that help the immune system fight pathogens like bacteria.

DNA does not serve as a direct energy source or storage molecule for energy; those roles are performed by carbohydrates (like glucose) and lipids (fats).

Answer:

  • DNA gives instructions on how to make keratin, the protein that makes up human hair and skin.
  • DNA contains information about eye and fur color that is passed on from parents to kittens.
  • DNA helps create substances that fight the bacteria that enter the body.
